Introduction: In this study, we examined the role of immunological factors on sudden sensory neural hearing loss (SSNHL).   Materials and Methods: This prospective case-controlled study was performed in patients with SSNHL who referred to the ear, nose, and throat (ENT) ward. Fifty-six patients with SSNHLoccurring within a 72-hr period were selected as the case group and 56 participants who ha...

Antinuclear antibodies (ANA) represent the main diagnostic markers for systemic autoimmune disease (AD), although their presence can be detected in blood donors. The aim of this study was to study ANA prevalence in healthy subjects of different racial groups, exposed to the same environmental factors, in order to understand the relevance of genetics or environment in determining autoimmunity. W...

Immune factors are currently believed to be important in the pathogenesis of rheumatoid synovitis. Several findings have suggested that immune mechanisms are operative within the rheumatoid joint; these include the detection of antiglobulins and low levels of complement in the synovial fluid (Hannestad and Mellbye, 1967; Ruddy and Austen, 1970), the detection of immunoglobulins and complement w...

A review of five years' DNA-binding antibody results in a routine service laboratory revealed 38 patients who had high DNA-binding capacity (DNA-bc) but no antinuclear antibodies (ANA). On retrospective case note analysis, 22 patients (58%) were thought to have systemic lupus erythematosus (SLE), although only six (16%) fulfilled the preliminary classification criteria of the American Rheumatis...

The results of antinuclear antibody tests using the indirect immunofluorescence technique may be reported as a description of the pattern and the intensity of fluorescence obtained at a certain dilution. If quantitative results are required titration is necessary. Such titrations may vary greatly between different laboratories. The present study involving 26 laboratories shows an improvement of...

We analyze the case of a 49-year-old male patient who presented with clinical signs acute hepatitis an initial suspicion autoimmune etiology. Laboratory findings demonstrated positive antinuclear antibody, anti-smooth muscle antibody and high serum gamma globulin. Histology liver biopsy revealed changes compatible hepatitis, which associated International Autoimmune Hepatitis Group score 7, det...

UNLABELLED Overlap of systemic lupus erythematosus and autoimmune hepatitis is a rare condition, occasionally described. Both autoimmune diseases can share common autoimmune features such as polyartralgia, hypergammaglobulinemia and positive antinuclear antibody, but they have been considered as two different entities. We report a 14 year old female patient with systemic lupus erythematosus who...
